Which sounds are called noise?

Is sound a vibration?
Sound is a type of energy made by vibrations. When an object vibrates, it causes movement in surrounding air molecules. These molecules bump into the molecules close to them, causing them to vibrate as well.
Which are types of insulation help reduce noise?
Blankets and Batts. The rolls of fiberglass and mineral fiber insulation used to prevent thermal transfer through the walls of a building also serve as a form of acoustic insulation.
What is sound and noise?
Noise is unwanted sound judged to be unpleasant, loud or disruptive to hearing. From a physics standpoint, noise is indistinguishable from sound, as both are vibrations through a medium, such as air or water. The difference arises when the brain receives and perceives a sound.
What is active noise reduction?
Active noise control (ANC), also known as noise cancellation, or active noise reduction (ANR), is a method for reducing unwanted sound by the addition of a second sound specifically designed to cancel the first.
